Find the truth within the past

"What the fuck?" I said.
"Hey stop cursing!" I rolled my eyes. "Look there, something is happening." Elio said and ran off.
"Wait- we don't know what that could be-"
As soon as i saw who it was i couldn't belive it. All of the 6 ninja standing right in front of us. It seemed like they caught a criminal or something. I'm not really sure.
They all looked so young, and to be honest, they were all so beautiful.
"ELIO! WAIT UP!" I started yelling cause now he was approaching the ninja.
I jumped at him, causing him and me to fall right in front no other than ninja themself. Aunt Nya to be exact.
--------
Alanze and Elio are kids from no other than past earth and fire ninja. What happens if one day the two get stucked in the past, when everything was still in danger; the criminals, thugs... Will they find out how their parents got together or will their presence affect the future?
(Timeline in the past is after the merge, when they're all together, Kai never disappeared)
(Don't ask me how the kids got their genes and elemental powers, they just did☺)
